The Fed's second round of quantitative easing (QE2) can boost commodities prices through four channels. First, by depressing Treasury yields in the middle of the yield curve and (it is hoped) by inflating prices generally, it can exert downward pressure on the U.S. dollar against other currencies such as the euro.

Of course, this would boost global commodities prices in dollar terms only (it would have the opposite effect on prices in euro terms, for example).

This tranmission channel pertains to all segments of commodities. Equally, it pertains to all other traded goods and services priced in U.S. dollars. QE2 is aimed, after all, at inflating dollar prices.

Second, by generating confidence that the U.S. economy will avert deflation and thus stir up hopes that growth will take off, it can draw speculators into the futures markets for industrial commodities: energy commodities and base metals.

Third, by generating fear of hyperinflation even while boosting high hopes for industrial commodities (in an unusual confluence of events), it can provide support for precious metals. Of course, this support will be iffy and unstable, as with any price support that relies on mere raw feelings such as fear.

Fourth, by depressing Treasury yields (in the middle of the curve), it can draw investors desperate for yield into the asset class.
